Noise suppression with high Mach number inlets [PDF]
Experimental results were obtained for two types of high Mach number inlets, one with a translating centerbody and a fixed geometry inlet (collapsing cowl) with no centerbody. The aerodynamic and acoustic performance of these inlets was examined.

Simulation of Hollow‐Core Photonic Crystal Fibre‐Based Photothermal Spectral C2H2 Gas Sensor
High Voltage, EarlyView.ABSTRACT Fault characteristic gas analysis is one of the important methods for monitoring the operating status of power equipment. This study presents the construction of a simulation model for a hollow‐core photonic crystal fibre (HC‐PCF)‐based photothermal spectroscopy gas detection system.

Journal of Applied Ecology, EarlyView.A framework for the support of pollinators in urban areas is developed here, based on five pillars: nesting, flower resources, artificial support, management and society acceptance, with additional key elements from science and society. Society should incorporate strategies for pollinators as in this framework by means of co‐planning with stakeholders,

Flight investigation of XB-70 structural response to oscillatory aerodynamic shaker excitation and correlation with analytical results [PDF]
The low frequency symmetric structural response and damping characteristics of the XB-70 airplane were measured at four flight conditions: heavyweight at a Mach number of 0.87 at an altitude of 7620 meters (25,000 feet); lightweight at a Mach number of 0.

Gender &History, EarlyView.ABSTRACT This research focuses on how the North Korean Democratic Women's Union (NKDWU), the umbrella women's organisation in North Korea formed soon after Korea's liberation from Japanese colonial rule in 1945, forged international leftist women's solidarity during the North Korean state's liminal, revolutionary period (1945–1949).

High Reynolds Number Test of the Boeing TR77 Airfoil in the Langley 0.3-Meter Transonic Cryogenic Tunnel [PDF]
A Boeing TR77 airfoil associated with the Advanced Technology Airfoil Test (ATAT) program was tested in the Langley 0.3 m Transonic Cryogenic Tunnel. Limited analysis of the data indicated that increasing Reynolds number for a fixed Mach number resulted ...

Human Resource Management Journal, EarlyView.ABSTRACT The context in which careers develop is attracting increasing scholarly attention. Building on career ecosystem theory, we examine how societal and organizational actors within career ecosystems influence the development of careers. In our study of university leaders in 60 countries, we find that career trajectories are more similar within ...

Molecular Ecology Resources, EarlyView.ABSTRACT Environmental DNA (eDNA) metabarcoding technologies promise significant advances in biodiversity monitoring, yet their application requires extensive optimisation and standardisation. Recent research demonstrated that increased sampling and analytical efforts are needed to improve biodiversity estimates, though fully optimising study designs ...

Ground Measurements of Airplane Shock-Wave Noise at Mach Numbers to 2.0 and at Altitudes to 60,000 Feet [PDF]
The intensity of shock-wave noise at the ground resulting from flights at Mach numbers to 2.0 and altitudes to 60,000 feet was measured. Meagurements near the ground track for flights of a supersonic fighter and one flight of a supersonic bomber are ...

Improving Whole Biodiversity Monitoring and Discovery With Environmental DNA Metagenomics
Molecular Ecology Resources, EarlyView.ABSTRACT Environmental DNA (eDNA) metagenomics sequences all DNA molecules present in environmental samples and has the potential of identifying virtually any organism from which they are derived. However, due to unacceptable levels of false positives and negatives, this approach is underexplored as a tool for biodiversity monitoring across the tree of
